Rocket Fuel Grains

CSEF · 2014 Applied Mechanics & Structures

Alessandro Panighetti · Ventura High School, Ventura, Ventura County

Overview

Objectives/Goals the objectinve of my experiment was to determine the effects of the rocket fuel grain on the thrust provided over time Methods/Materials For the experiment I used a hybrid rocket which consumed polyvinyl chloride and oxygen as fuel. To measure the force provided I allowed the rocket to push against an electronic scale and recorded the results. Results In my experiment I tested 4 fuel patterns the single and double port fuel grains began with little power and slowly built up to a more powerful burn the other two fuel grains did not fire properly Conclusions/Discussion In conclusion in my experiment I have determined the burn pattern of two fuel grain types and also determined that the other two cores tested began with enough force to stop the flow of oxidizer due to the back pressure

Summary statement

the focus was to determine the effects of the rocket fuel grain on the thrust provided over time
